Update Dynamic Title when value is changed in input

Hi All,

I’m sure this is a simple one. I have a title with a dynamic data binding in it. The data bind pulls a value X from a server action file. I also have a text input with default value of Y. When the page loads the title multiplies X by Y and prints the value. However I would like the user to be able to input a different number in the text input and for the title to dynamically update. I’m sure I’m missing something simple here.

Thanks in advance everyone.
Ivan
